无法更改XSL-FO中列表项之间的空间

Question

它似乎没有出现provisional-label-separation属性影响间距.我也试过margin-*,padding-*,space-before,和space-after而列表项之间的空间仍然不会改变.如何更改列表中列表项之间的垂直空间(如果这有所不同,我将渲染为PDF)？

<fo:list-block provisional-distance-between-starts="3mm" 
               provisional-label-separation="3mm" 
               space-after="3mm" >

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Day care or nanny expenses</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Field trips</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>School supplies</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Music lessons and other extracurricular activities</fo:block>
        </fo:list-item-body>
    </fo:list-item>

</fo:list-block>

要更改列表项之间的垂直空间,使用space-after(或者space-before)在列表项:

<fo:list-item space-after="5mm">
  <fo:list-item-label end-indent="label-end()">
     <fo:block>&#x2022;</fo:block>
  </fo:list-item-label>
  <fo:list-item-body start-indent="body-start()" font-size="9pt">
       <fo:block>Day care or nanny expenses</fo:block>
  </fo:list-item-body>
</fo:list-item>

provisional-label-separation指定list-item-label的结尾与list-item-body的开头之间的临时距离(即,它是水平距离).见http://www.w3.org/TR/xsl/#d0e12377.
